I know everybody loves to say how careful you need to be shooting wide open and recomposing, but I really don't think that's the problem here.

Right.  I'm just saying that this is a focus problem, and to track it down you'll need to be extremely careful about camera movement.  And I'll repeat, your DoF is not 1ft when examining images at 100% magnification -- it is much less than that.

I would suggest setting up a simple target to check AF accuracy.  A small box sitting on a patterned surface would be ideal.  Set the camera on a tripod with the selected AF point aimed at the side of the box.  The patterned surface will tell you where the DoF is in relation to the box.

Try different AF points and check each for consistency.  Let us know what you find.
